Hi got a new wifi last week. I tried to connect my Tapo L510E bulb, but it wouldn't work. I used the Tapo app to remove the bulb, then tried to add it again. Didn't work. 

I have followed the steps, tapped that the bulb did not blink. No help. 

I have tried to re set it, switching off and on 3, then 5 times. No help. 

The bulb is not showing on either my phones Bluetooth or WiFi networks. 

The bulb still lights up, but won't connect to Tapo app, or Alexa anymore. 

Is there anything that I haven't tried?
